How to stick a sticky note

by Martin Schapendonk on May 17, 2013 · 1 comment

While doing my work in a lean and agile way, I work with sticky notes quite often. When sticked to a wall or whiteboard, it is quite crucial that they do not move until I want them to. Unfortunately, it sometimes happens that the sticky notes fall down to the ground… What a disaster!

March 7, 2013

In one of my projects we have to be able to set up a (cold) backup Oracle Service Bus domain in a different data center from a domain backup.

Monitoring Business Objects end user activity using Oracle Enterprise Manager

February 25, 2013

Recently, one of our clients upgraded their Business Objects environment to version 4. Reports are run on datamarts in the datawarehouse, but there are also older reports running directly on operational databases. From an instrumentation perspective, we couldn’t see what was going on exactly using the Oracle Enterprise Manager during the day.

Slow loading of tabular forms in Application Express

October 11, 2012

Under some circumstances, there is an issue (observed in Application Express 4.1.1.00.23) that page tabular forms take very long to load, up to several minutes. Even if there is a very small dataset in the underlying table.  When I encountered this issue, the report ran fine on Development en Test environments, but in the almost identical production environment the page took minutes to load.
